Drivable Grass is a flexible product that can be used as a substitute for concrete and asphalt driveways, patios, parking lots, RV pads, boat ramps, and the like.

InFuez, Inc., the maker of Fuez solid slab surfaces, is being mentioned more and more these days (first noticed in the Portland SIPs House).
